APPARATUS FOR'CALKING SEAVIS OF VESSELS.

SPECIFICATION formingpart of 'LettersPatent No.` 725,340, dated April14,- 1903.

Application filed June 1.0, 1901.

To a/ZZ whom t may concern:

Be it known that I, CHARLES G. HIGH- TOWER, a citizen of the UnitedStates, residing iu the city and county of San Francisco, State ofCalifornia, have invented certain new and useful Apparatus forCalkingSeams v f Vessels; and IV do hereby declare the following to be afull, clear, tion of the same.

The present invention relates to a new and useful apparatus for use incalking seams of ship-decks or work of like character orv where it isdesired to make water-tight the opening between planks; and the objectof the inven tion is to enable the oakum or calking material to bedriven with greater rapidity, more uniform, and with compactnessunattainable by hand-calking The calking of vesselsl is at present doneby hand, expert calkers being required for such purpose. As a result theoakum is not driven with uniformity, inasumch as itis impossiblefor thecalker to drive the oakum with an even blow throughout the entire work.However, the main objection to this manner of calking is the slownesswith which the lwork is accomplished and the expense attached thereto,as an expert calker is un; able to cover more than about one hundred andfifty feet for a days work. In addition to the calker an expert puttieris required to putty the calked oakum after the calker has completed hisportion of the work, and where` the work is to be performed upon an oldvessel a workman must be employed to remove the old oakum from the seamsbefore the calker is enabled to apply. the vnew oakum therein. Thesevarious steps require that much time be devoted to the work of properlycalking a vessel and the expenditure of considerable money therefor. l

While the present invention performs the work of calking the seam, it islikewise adapted to apply putty to the calked seam, and in case of anold vessel being recalked means are provided for removing the old oakumfrom within the seam, so as to clear the same in advance of the calkingmechanism.

Practical experience has demonstrated that by the employment of thehereinafter-described apparatus about Iifteen hundred feet and exactYdescripseriiu No. 63,907. Nt model.)

may be successfullycalked-and puttied in one day, and that without theaid of expert calkers. Y..

The hereinafter-described apparatus is believed to bel theiirstautomatically-operated means whereby the work of calking the seams ofvessels 'is mechanically performed by forcing theV oakum intothe seamunder a uniform pressure. Y Hence the intent is to cover this featurebroadly, whether the apparatus be employed simply for the operation. ofcalking orin connectionwith the reaver and puttier attachments or incombination with either of said attachments.

In orderto comprehend the invention, reference should be had to theaccompanying sheets of drawings, wherein- Figure 1 is a side View of thecalking appavratus with the reaver attachment for removing the old oakumand the attachment whereby the calked seam is puttied applied thereto.Fig. 2 is an enlarged longitudinal sectional top plan view taken on-line rx, Fig. 1, the reaver and puttier attachment being xremoved.

The numeral 1 is used to indicate the frame or base plate of themachine, supported by the rollers 2 and 3. The frame or base plate hassecured thereto the uprights or standards 4 4', which carry the cylinder5. In the present case the frame-plate, standards, and cylinder are madeintegral. This, however, is immaterial, as the said parts may be castseparately and united in any suitable manner. Within the cylinder 5works the piston 6, to the stem 6 ot which is connected the hammer 7.This hammer is provided with a removable head 8, which is dovetailedthereto. The hammer is provided with the side extensions 9, which workwithin the guides or Ways 10, cut in the inner face of the standards oruprights 4 4, Fig. 1 of the drawings. The hammer acts upon the stem 11of the calking-tool 12 during the reciprocating motion ot' the piston 6.Said stem 11 works within a sleeve 13, fitted in a Vertical opening 14in the frame or base plate 1, being held therein by the tightening-screw15. The tool is prevented from dropping out of its sleeve or shell bymeans of the screw 16, extending therethrough and into a vertical slot17, cutin the face of stem 11. The said stem is held upward by thepressure of the recoilspring 17', which bears against its enlarged head12. Thus the calking-tool is normally held out of and above the seam tobe calked and, being spring-actuated, automatically returns with theupward movement ol' the hammer, Fig. 6 of the drawings. In the presentcase the calking-tool is detachably connected to its stem 1l.Consequently the tool may be removed therefrom for any desired purpose.y

The cylinder 5 is provided with the inlet and outlet openings 18 19,Fig. 12 of the drawings, which openings are controlled by the rotatablecage-valve 20. This valve is open at its bottom, and through the sidewall thereof the inlet and outlet ports 20 2l are cut, which register,respectively, with the openings 18 19 of the cylinder. Vhen port 21registers with opening 19, so as to open same, port 20' is out ofregister with opening 18 and said opening is held closed. This valve isrotated in order to open and close said ports during the stroke of thepiston G, its fiat stem 22 working within the hollow portion 23 of thepiston. This stem 22 is formed with a twist, and it extends through theelongated opening 23 in the end plate 25 of the piston.

The cage-valve rests upon the seat 26 and is held in place againstlongitudinal movement by the cylinder-head 2G'. During the reciprocatingmovement of the piston the valvestem 22 is turned to the right or left,depending upon the direction of the pistons stroke. Inasmuch as the stemis rigid with the cagevalve, the movement of said stem rotates thecage-valve 20, so as to open or close inlet and outlet openings 18 19.

In the wall of the cylinder is the passageway 27, which leads from theinlet-opening 18 and communicates with the intcriorof the cylinder at apoint below the downstroke of the piston. With the inlet 18 is connectedthe main supply-pipe 28, Figs. 1, 2, 10, and 12 of the drawings. Thissupply-pipe is provided with a valve 29, by means ot' which theadmission of the motive fluid to the main cylinder is controlled.

Any suitable motive power may be utilized to operate the apparatus,although pneumatic or compressed air is preferred. An air-compressor(not shown) is located at any convenient point, and the compressed airis supplied by means of the flexible tube 30, which connects theair-compressor with the main supply-pipe 28.

The supporting-rolls 2 3 are secured to axles 30'31, which work inbearings of the frame or base 1. In the present case the rolls 2constitute the drive-rolls of the apparatus, being driven by the worm32,'which meshes with worm-gear 33, mounted upon axle 30'. The worm 32is carried by the wormshaft 34, which shaft works within the tilbularcasing 35. This casing is fulcrumed by pin 3G to the upright or standard4', Figs. 1 and 3 of the drawings.

The upper end of the worm-shaft 34 is attached to the bracket 36',located within the motor-casing 37. Said bracket carries the gears 3839, which are driven by the intermeshing pinion 40, Fig. 13 of thedrawings. This pinion is attached to spindle depending from disk 42within the casing, said spindle extending through a central opening inthe diaphragm 43, which divides the casing. Within the casing andattached to the disk 42 are located the air-cylinders 44, in each ofwhich works a piston. This constitutes an airmotor of well-recognizedtype, and specic description thereof and as to its workings is notrequired. The casing t is formed with an air-inlet port 48,'through IOOIIO

which air is admitted for the working of the i pistons of theair-cylinders, the air under pressure entering the cylinders through theports 49. The exhaust from the cylinders makes its escape from thecasing through the opening 42'.

To the air-inlet port 48 connects the hose 50, leading from point 51 ofthe branch airsupply pipe 52. By means of the valve 52 the supply of airto the drive-motor is controlled. This branch supply 52 is connectedwith the main supply-pipe 28, the flow of air from said main supply-pipethrough the branch supply-pipe into hose 50 being regulated by the saidvalve52'.

From points 54 55 56, respectively, of the branch pipe extend the` hoseconnections 57 58, and 59, the two former of which connect with theputty-cylinder 60, while the latter connect with the air-motor` 61 fordriving of4 the reaver attachment. 'lhe putty-cylinder 60 is supportedin brackets 62, extending from standard or upright 4', while the motor6l is held within bracket 63, extending from standard or upright 4,which bracket also supports the oakum-reel 64, Fig'. 1 of the drawings.

, By preference the putty-cylinder is made in sections 66, united bybolts 67', the sections being separated by diaphragm 68. In the lowersection 66 of the cylinder is placed the putty which is to be deliveredto the seam after the oakum has been driven therein. Within the lowercylinder-section works the piston 69, while in the upper .section oftheA cylinder works the piston 70. These pistons are connected by stem71, and they are gradually forced downward'hy the pressure ofthe airentering the cylinder from 'the connections 57 and 58, that fromconnection 57 being admitted into the upper section above piston 70 andthat from connection 58 being admitted into the lower section above thepiston 69. The air thus admitted causes vthe pistons to move downwardand gradually force the putty from the lower section through itstapering outlet v72 into and through tubular extension 73. Thisextension is held within guide-openings 74, and to the lower end thereofis attached the putty-guide 75, Figs. l and 3 of the drawings. To raisethe pistons within the cylinder-sections, the hose connection 58 isdisconnected from inlet-pipe 75 and connect-` ed with pipe 76, whichenters the cylinder above diaphragm 68, and air thus admitted to thecylinder below piston 70, the pressure of which forcesf said piston. andpiston 69 through the medium of connecting-stem 7l -upward.A This isonly necessary when it is de- 80, respectively. During the downwardmovement of the pistons the exhaust or` outlet of the cylinder isthrough pipe 76, which is nor` mally an open one. To refill the lowersection ofthe cylinder with putty, the upper section is disconnected andthe piston removed therefrom, when free access may be had to theinterior of the lower section of the cylinder.

By means of the Valve the admission-of air from the branch supply 52through the connection 59 to the reaver-motor 61 is controlled. Themotor employed'for operating the reaver is the same as that described inconnection with the motor for driving the apparatus, Figs. lvand14'of-the drawings.

When used to drive the reaver,` the form of is dispensed with and thedepending spindle 78 of the rotating disk works in bearings of thebracket 81v and4 has secured thereto `the gear-wheel 82. This gear-wheelmeshes with pinion 83, secured to the upper end ofdriveshaft 84, whichshaft extends through guideopening in bracket 81 and guide-opening,

85 in bracket 86, extending laterally from frame 87. To the lower endfportion of the drive-shaft is keyed or otherwise secured the crowngear-wheel 88, which meshes lwith crown-pinion 89 of lcross-shaft 90.This crossshaft works in the adjustable bearing-boxes 91, fitted toslide between the arms 92 of the frame'87. Said boxes are raised andlowered by means of the screw-bolts 94. Upon the v cross-shaft90.between the adjustable bearing-boxes is secured the reaver 95, whichis held a slight distance in advance of the gage-- lplate 96.

The reaver is in line with the seam to be calked during the operation oftheivapparatus, and its function is to remove from the seam the oldoakum and putty, thus pre-4 senting a free seam tobe calked. When theseam is that of a new vessel or beingcalked for the first time, thereaver is not necessary.

In such case it may be raised clear of thev seam or the entire reaverattachment may be removed.

vIn the main frame or base plate near-each end the cylinders 97 and 98are located.l

Within cylinders 97 works piston 99, which is held outwardly ordownwardly pressed by.

spring 100. The stem 101 of each piston projects beyond the cylinder andits lower'end is bifurcated, and between the arms of stem working incylinder-97 theguide-roll 1O21is held. This guide-roll iits within theseam to IOO be calked and guides theapparatus, so as to Y hold thecalking-tool in line therewith. To said stem in advance of theguide-roll is attached the gage-plate 96, which works in the seam to becalked in advance of the forward guide-roll. The object of saidgage-plate is to clear the seam` of loose putty or oakum left g by the.reaver.

Between the cylinders 97 98 are located cyl- I inders 98', and in eachof said cylinders works the piston 103, held down t by4 spring 104.

The stem 103 of said pistons, like those of` pistons 99, extends' belowthe main frame or base plate, and the-lower end of each stem isbifurcated and carries between its arms the roll 105, said roll having agrooved periphery.

`The forward roll acts as'feed-roll for-the These rolls kare carried bythe stems 109 110 of pistons 111, which work within cylinders 113. Thesepistons are held upward within the cylinders by springs 115, so that therolls 107 108 are normally held clear of the deck. When the pistons areforced downward, the rolls 107 108 bear against the deck and raise orjack the entire apparatus clear thereof. As thus raised a workman byexerting slight pressure thereon may easily roll the apparatus to theseam to be calked. The rolls 107 108 are lowered by the air-pressureadmitted to cylinders 113 above the pistons 111. Air is supplied to the.cylinders through ports 116 117 by means of the connections 118 119,which connections are attached to the branch supply-pipe at points 120121, respectively. The supply of air to the cylinders is controlled bythe three-way valve 122, which admits air from the branch supply-'pipeto the connections simultaneously. At the same time air is admittedwithin the cylinders 97,

98, and 98 in order to raise the stems 101 y and 103 and the rollscarried thereby. The air is admitted below the piston of each cylinderthrough the couplings 123 124, which connect, respectively, with thesaid cylinders and the connections 118 119. the three-way valve 122 isturned to cut ofi. the supply of air from the branch supplypipecommunication is established between the connections 118 119 and theexhaust 125 of said branch supply. The pressure of springs 100, 104, and115 returns the pistons to their normal position, the air from the cylisired that the oakum be oiled, so as to preinders escaping throughexhaust 125.

The thread of oakum as unwound from the reel 64 passes throughguide-tube 126 to thel feed-roll 105 and is held in proper positionbelow the calking-tool 12 and presented in a straight line thereto bymeans of the shoe 126. This shoe is provided with a tool-opening 127 inits bottom and is supported below frame 1 by means of the rods 128,which work within seats 129 and are held pressed outward by springs 130.By mea-ns of these springs the shoe is held firmly pressed against thedeck being calked. Within this shoe is located the tucker-wbeel 131,which is mounted upon the shaft 132. This wheel engages the oaku m fedthrough the shoe and tucks or bunches same within the shoe over theoutletopening. The object of thus tucking orbunching the oakum is that aball, so to speak, of oakum may be presented to the action of thecalking-tool in case of a wide seam and necessity of repeating the actof calking avoided, which would bue required in case onlya strand ofoakum should be driven into the seam at each stroke of the calking-tool.By thus tucking or bunching the oakum a suiicient quantity of oakum isdriven into the seam with each stroke of the tool to fill the same. Thetuckerwheel is actuated by the stroke of the hammer 7. This hammercarries a lug 133, which during its upstroke engages with the collar134, secured to rod 135, and lifts the said The moment y i pawlmechanism and the travel of the tuckerwheel with each throw of the saidmechanism vaas-io rod a given distance. Said rod is connected at itslower end to link 136, Figs. 3 and 9 of the drawings, which link isloosely mounted .upon shaft `137. To the rod 135 is attached the pawl138, which engages with the pawlgear 139, secured to shaft 137. Witheach upward stroke of the hammer the rod 135 is lifted, which in turnthrough its pawl mechanism rotates the gear 139.

The rotation of this gear im parts a corresponding rotation to shaft137, which carries the larger gear 140. This gear meshes with pinion141, so as to impart'rotation to shaft 132, to which the tucker-wheel131 is secured. Thus with each upward stroke of the hammer 7 it will beseen that the tncker-wheel is driven by a step rotation. The length ofthe stroke of rod 135 may be increased or decreased by means of thelever 142, fulcrumed to one of the standards of the apparatus, Fig. 15.This lever is connected at its outer end to upper end of the rod 135,and at its inner end portion is provided with the spring-catch 143,which catch engages with quadrant 144. By raising or lowering theactuating-rod 135 through i its adjusting mechanism the distance of colllar 137 from lug 133 is increased or decreased and a longer or shorterthrow imparted to the correspondingly increased or decreased. The

l tucking or bunching of the oakum is heavy given the tucker-wheel.

During the operation of calking it is deserve the life thereof while inthe seam. For this purpose there is an oil passage-way 145 formed in theseats 129, Figs. 1 and 7 of the drawings, with which connect oil-tubes146. These tubes lead from the oil-cup 147. The oil fed to the seats 129gradually escapes therefrom and satu rates the oakutn held Within theshoe 126. i

It is possible that during the work of calking the calking-tool 12 maystick in seam 148 of deck 149 when driven therein by the hammer 7 andthe pressure of recoil-spring 17 be insufficient to raise the tooltherefrom. To provide against this, there is attached to the head 12 oftool-stem 11 the lift-rod 150,

Fig. 1 of the drawings. In this rod is cut a slot 151, within whichworks a lug 152, projecting from the hammer 7. This lug 152 in case thepressure of recoil-spring 17 should prove insufficient to remove thecalking-tool during the upstroke of the piston 6 engages with the upperend of slottedlift-rod prior to the piston completing its upstroke andcarries the same therewith. This upward movement of the lift-rodsuflices to release the calking-tool from the seam, when the pressure ofthe recoil-spring will return the tool to its normal position.

As the hammer is driven at a high rate through the medium of theactuated piston 6, the calking-tool will have correspondingly a IOO lIO

' and as the blow of the hammer is a `uniform onethe oakum will bedriven into the seam 148 under an even. and muclrgreater pressure thancan be obtained by hand-calking. During the operation of calkin g theapparatus is driven longitudinally by means of thehereinbefore-described worm mechanism along the deck. As the apparatusperforms the work of calking Yputty isforced from the putty-cylinder 60by the air-pressure acting upon the pistons 69 70 through extension 73and guide 75 onto the oakumfwithin the seam. The putty thus forcedwithin the calked seam is properly smoothed and pressed by the spreaderv153, secured to the lower end of stem 101, working withincylinder 98,Figs. 1 and 3 of the drawings. t,

In case the'deck to be puttied is a new one then the reaver attachmentis not required, and the same may be removed from the apparatus or thereaver raised by its adjusting devices, so as to clear the deck to becalked. The reaver attachment is' only designed .for use duringthecalking of old seams or such seams as require the old oakum to beremoved. Y

It is not required that the puttier be used at the same time as thecalking mechanism, although it is preferred so to use same. If desired,Vthe Work of calking may .be completed and the puttying done thereafteras a distinct operation.

operations vmay beperformed--to wit, the

reaving of the old oakum, calking of the oakum, and puttying of thecalked seams. These .operations can be conducted at the Sametime orseparately, as the Work mayrequire.

When desired to stop thelongitudinal travel of the apparatus, the worm32 is thrown out of mesh with Worm-gear 33 by means of hand-lever 154.Thishand-lever is attached to eccentric 155, over which fitsv link 15.6.Said link is connected to lower end portion of fulcrumed casing 35,which contains the worm-shaft 34. As the hand-lever 154is thrown upwardthe eccentric .155, is turned so as to draw the link 156 inward. Theinward movement of said link carries the lower end of :casing 35therewith and places worm 33 out of mesh with its worm-gear. thrown outof gear, travel o f the apparatus ceases.

The operation of the-various parts is controlled by the admission of theair from vthe main supply-pipe tothe respective pistons and motors. s

As before stated, any suitable style of mechanism may be employed forimparting motion to the apparatus and operating its various parts,although compressed air is preferr-ed, owing to itsease of handling.

The air for operatingthe calking-tool Ais admitted to the cylinder '5above and Vbelow the piston-head Gthrough portZO'` and pas- When thussage-way 27. While port 20' is opened the air admitted to the cylinderthrough passageway 27 is sufficient to. forman ai r-cnshionforthedownstroke of the piston. The moment the said port is closed the fullpressure of air is admitted through said passage-way in order toforce-the piston upward. i
